Perfect Squares and Square Roots: Understanding and Finding Them

The video tutorial explains what perfect squares are and how to find their square roots. It begins by defining a perfect square as a number that can form a square using 1 by 1 unit squares. The tutorial provides examples of perfect squares, such as 4 and 9, and explains why numbers like 5 and 6 are not perfect squares. It also includes practice problems to help viewers identify perfect squares and their square roots. Finally, the video demonstrates how to create perfect squares by increasing the side length of a square incrementally.
